Question

我是 Python 新手。我安装了 miniconda 来获取软件包 iminuit 和 minuit。为此，我创建了一个新环境以避免冲突。但是当我尝试使用命令安装 minuit 时

conda install minuit -c conda-forge

我收到以下错误消息：

Collecting package metadata (current_repodata.json): done
Solving environment: failed with initial frozen solve. Retrying with flexible solve.
Collecting package metadata (repodata.json): done
Solving environment: failed with initial frozen solve. Retrying with flexible solve.

PackagesNotFoundError: The following packages are not available from      current channels:

 - minuit

Current channels:

 - https://conda.anaconda.org/conda-forge/osx-64
 - https://conda.anaconda.org/conda-forge/noarch
 - https://repo.anaconda.com/pkgs/main/osx-64
 - https://repo.anaconda.com/pkgs/main/noarch
 - https://repo.anaconda.com/pkgs/r/osx-64
 - https://repo.anaconda.com/pkgs/r/noarch

To search for alternate channels that may provide the conda package     you're
looking for, navigate to

 https://anaconda.org

and use the search bar at the top of the page.

我该如何解决这个问题？

Answer 1

正如消息所说，该软件包在当前频道中不可用。如果您查看 anaconda.org，您会发现：

https://anaconda.org/mutirri/minuit 表示：

<块引用>

要使用 conda 安装此软件包，请运行以下命令之一：
conda install -c mutirri minuit
conda install -c mutirri/label/all minuit

Answer 2

我不确定 CERN 的 ROOT 包的版本，但我猜他们不再支持 Minuit 包，而是支持 is more lightweight and Jupyter friendly 的 Imminuit。

所以你可以用这个命令安装这个包，根据here：

conda install -c anaconda iminuit

安装ROOT时出错
